3. Insert the MPH2 rack PDU screw into the spacer sleeve.

4. Insert the MPH2 rack PDU screw into the spring nut and tighten securely with a flat-head

screwdriver.

5. Hang the RPC BDM on the screw with the hooded mounting slot on the back of the RPC BDM.

6. Connect the RPC BDM to the RPC2 with an Ethernet cable.

7. Be certain to connect the cable to the correct port on the RPC2.

2.5.2 Temperature/Humidity Sensor

Optional Liebert

SN temperature/humidity sensors are available to assist in monitoring conditions

in the rack. Liebert SN sensors are designed for installation in Emerson racks without tools, but each

may be placed in any area to monitor temperature and humidity levels. Each connects to the RPC2

communications module, which makes readings available to other monitoring methods.

To install a sensor in a rack:

1. Insert the sensor bracket base into one end of the sensor support.

2. Snap the sensor into the other end of the sensor support.

3. Choose where in the rack to install the sensor assembly.

4. Hold the sensor bracket on a T-slot on the Emerson rack frame where the sensor will be placed.

5. Insert the included quarter-turn fastener through the rectangular hole in the sensor bracket base

and into the T-slot.

6. Turn the fastener clockwise 90 degrees, a quarter of a turn.

7. Route the sensor cable to the RPC2 communications module and insert it into the card’s external

sensor port.

NOTE

Emerson recommends placing the sensor in the area of the rack that is likely to be warmest.

That location helps determine extreme conditions that can cause equipment damage.
